Description

Specification: 13.8*350*7
Material: 55SiCrA oil-quenched wires

The RD5 rear spring 52441-S9A-014 is the after-sales part number of the rear coil spring of Honda CR-V (chassis codes RD5/RD6) 2001 to 2006. Though it belongs to the same mold series as the earlier versions -003/-013, its dimensions and stiffness have been re-tuned to meet the increased weight and load-carrying requirements of the second-generation CR-V.
The coil spring has a steel wire diameter of φ13.8 mm, a height of 350 mm, an effective number of coils of 7, and linear stiffness ranges from 19 to 21 N/MM. The quantity required per vehicle is 2.

Honda RD5 specifically refers to the 2.0L version of the second-generation Honda CR-V 2001 to 2004, with its chassis code designated for the Chinese and Asian markets. 52441-S9A-014 is exactly the after-sales part number of the rear coil springs of this specific model.

The structural features and advantages of the RD5 Rear spring 52441-S9A-014 are as follows:
1) Matching between stiffness and vehicle weight: 20 N/mm, increased by 11% compared to an RD1 soft spring (18 N/mm), and no sagging under heavy loads
2) Double-layer corrosion resistance
Black epoxy spraying + PVC transparent sheath, which effectively prevents corrosion and is not prone to rusting
3) Separation of shock absorbers and springs: the springs bear pressure only and are not responsible for turning, so repair is cheap; and replacing the springs does not require disassembling a braking pipeline
4) High interchangeability: the same part is used for both the left and right sides, consistent with the dimensions of RD6 and early-stage -003/-013, so interchangeability is realized.
